A Critical Examination of Hypernova Remnant Candidates in M101. II. NGC 5471B
M101 kinematics and dynamics
2014/12/26
NGC 5471B has been suggested to contain a hypernova because of its extraordinarily bright X-ray emission. To assess its true nature, we have obtained high-resolution images in continuum bands and nebu...
XMM-Newton Spectra of Intermediate-Mass Black Hole Candidates: Application of a Monte Carlo Simulated Model
NGC 5408 NGC 628
2014/12/24
We present a systematic spectral analysis of six ultraluminous X-ray sources (NGC 1313 X-1 and X-2, IC 342 X-1, Ho IX X-1, NGC 5408 X-1, and NGC 3628 X-1) observed with the XMM-Newton observatory. The...
VLBI-selected sample of Compact Symmetric Object candidates and frequency-dependent position of hotspots
Galaxies: active – Galaxies: jets – Radio continuum: galaxies – Methods:numerical – Magnetohydrodynamics (MHD) – Shock waves
2011/9/27
The Compact Symmetric Objects (CSOs) are small (<1 kiloparsec) and powerful extragalactic radio sources showing emission on both sides of an active galactic nucleus and no signs of strong relativistic...
Context. In order to study the association of the origin of ultra high energy cosmic rays (UHECR) with active galactic nuclei (AGN) at all levels of their activity we require an unbiased sample of bla...
